Question: Given the following hypotheses: H 0 : = 400 H 1 : 400 A random sample of 12 observations is selected from a normal population.

Given the following hypotheses:

H₀: = 400

H₁: 400

A random sample of 12 observations is selected from a normal population. The sample mean was 407 and the sample standard deviation 6. Using the .01 significance level:

a.	State the decision rule.(Negative amount should be indicated by a minus sign. Round your answers to 3 decimal places.)

RejectH₀when the test statistic is(Click to select)outsideinsidethe interval(, ).

b.	Compute the value of the test statistic.(Round your answer to 3 decimal places.)

Value of the test statistic

What is your decision regarding the null hypothesis?

Reject

Do not reject
